Description

Technical Field

[0001] This utility model belongs to the field of pump casing processing technology, and relates to a jig for machining oblique holes in a pump casing machining center. Background Technology

[0002] The pump casing is the metal housing of a water pump, which is generally volute-shaped. It has multiple holes on its surface for connecting to its internal structure. When drilling the pump casing, the pump casing needs to be fixed on the machine tool using a clamping and positioning workpiece before drilling.

[0003] When using the above technology, the following technical problems were found in the existing technology: However, it is not convenient to adjust the angle of the pump housing after clamping it. When dealing with different angled hole processing, the adjustment is quite laborious. Moreover, for angled hole processing in different positions, the pump housing needs to be disassembled, moved, and then re-fixed, which seriously reduces the processing efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is that, currently, after clamping the pump casing, it is not convenient to adjust the angle of the pump casing. When dealing with different angled hole processing, the adjustment is quite laborious. Moreover, for angled hole processing in different positions, the pump casing needs to be disassembled, moved, and then re-fixed, which seriously reduces the processing efficiency.

[0005] This utility model discloses a slanted hole machining fixture for a pump casing machining center, comprising a machining base, a drilling mechanism fixed to the lower end of the top of the machining base, a fixed base fixed to the top of the machining base at a position between the drilling mechanisms, an adjusting shaft rotatably connected to the inner side of the fixed base, a connecting base fixed to the outer side of the adjusting shaft at a position in the middle of the fixed base, a connecting platform at the top of the connecting base, a fixed platform fixed to the top of the connecting platform, a placement platform fixed to the top of the fixed platform, clamping plates on both sides of the top of the placement platform, a clamping assembly on the inner side of the fixed platform corresponding to the clamping plates, and an adjusting assembly on the inner side of the fixed base for adjusting the angle of the fixed platform.

[0006] The adjustment assembly includes an adjustment handle, which is fixed at the end of the adjustment shaft away from the fixed base. A limit block is fixed at the position of the adjustment shaft inside the fixed base. A plurality of limit holes are evenly opened on the side of the limit block near the adjustment handle. A limit component is provided on the inner side of the fixed base at a position corresponding to the limit holes.

[0007] The limiting assembly includes a hollow screw, which is disposed on the outer side of the adjusting shaft near the adjusting handle. The hollow screw is rotatably connected to the adjusting shaft and to the fixed base. A limiting handle is fixed to the end of the hollow screw near the adjusting handle. An internal threaded cylinder is threadedly connected to the outer side of the other end of the hollow screw. The internal threaded cylinder is slidably connected to the fixed base. A connecting plate is fixed to the end of the internal threaded cylinder near the limiting block. The connecting plate is slidably connected to the fixed base. Multiple limiting bolts are fixed on the side of the connecting plate near the limiting block and at a position corresponding to the limiting hole. The limiting bolts are inserted into the limiting block through the limiting hole.

[0008] A limiting slider is fixed to the outside of the connecting plate, and the limiting slider is slidably connected to the fixed base.

[0009] The clamping assembly includes a bidirectional screw, which is disposed inside the fixed platform and rotatably connected to the fixed platform. Both ends of the bidirectional screw are threadedly connected to movable seats, which are slidably connected to the fixed platform. A support frame is fixed to the top of the movable seat, and the support frame is fixedly connected to the clamping plate. The support frame is slidably connected to both the fixed platform and the placement platform.

[0010] One end of the bidirectional screw extends to the outside of the fixed platform, and a clamping handle is fixed to the end of the bidirectional screw located outside the fixed platform.

[0011] The lower end of the fixed platform is fixed with a connecting shaft, the lower end of the connecting shaft extends to the inner side of the connecting platform, the connecting shaft is rotatably connected to the connecting platform, a rotating gear is fixed at one end of the connecting shaft located inside the connecting platform, a drive motor is fixed at the inner side of the connecting platform and near the rotating gear, a transmission gear is fixed at the output end of the drive motor, and the transmission gear is meshed with the rotating gear.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: through the structural design of the adjustment component, the adjustment shaft can be rotated to drive the connecting base to rotate around the adjustment shaft. The connecting base drives the fixed platform to rotate through the connecting table. When the fixed platform rotates, the workpiece held on the top of the placement table by the clamping component and clamping plate can be adjusted, thereby facilitating the drilling of the workpiece by the drilling mechanism to perform oblique hole processing. There is no need for the operator to disassemble and reinstall the workpiece, which effectively improves the processing efficiency.

[0013] The design of the connecting shaft, rotating gear, drive motor, and transmission gear allows for precise machining of different positions on the workpiece. Starting the drive motor rotates the transmission gear, which in turn drives the connecting shaft via the meshing rotating gear. This rotation of the connecting shaft, in turn, rotates the fixed platform and the workpiece positioned on top of the platform, thus adjusting the workpiece's position and effectively improving the device's practicality and processing efficiency.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0022] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0023] Example 1

[0024] like Figures 1-5 As shown, the system includes a processing base 1, a drilling mechanism 3 fixed to the lower end of the top of the processing base 1, a fixed base 4 fixed at the top of the processing base 1 and between the drilling mechanisms 3, an adjusting shaft 10 rotatably connected to the inner side of the fixed base 4, a connecting base 9 fixed at the outer side of the adjusting shaft 10 and in the middle of the fixed base 4, a connecting platform 8 at the top of the connecting base 9, a fixed platform 2 fixed at the top of the connecting platform 8, a placement platform 5 fixed at the top of the fixed platform 2, clamping plates 6 on both sides of the top of the placement platform 5, a clamping assembly at the inner side of the fixed platform 2 and corresponding to the clamping plates 6, and an adjusting assembly at the inner side of the fixed base 4 for adjusting the angle of the fixed platform 2.

[0025] By adjusting the structural design of the component, the adjusting shaft 10 can be rotated, causing the connecting base 9 to rotate around the adjusting shaft 10. The connecting base 9 then drives the fixed platform 2 to rotate via the connecting platform 8. When the fixed platform 2 rotates, the workpiece held on the top of the placement platform 5 by the clamping component and the clamping plate 6 can be adjusted, thus facilitating the drilling of the workpiece by the drilling mechanism 3 to perform oblique hole processing. This eliminates the need for workers to disassemble and reinstall the workpiece, effectively improving processing efficiency.

[0026] To facilitate the rotation of the adjusting shaft 10, the adjusting assembly includes an adjusting handle 12. The adjusting handle 12 is fixed at the end of the adjusting shaft 10 away from the fixed base 4. A limit block 11 is fixed at the position of the adjusting shaft 10 inside the fixed base 4. To facilitate the limiting of the rotation of the adjusting shaft 10 by the limit block 11, a plurality of limit holes 14 are evenly opened on the side of the limit block 11 near the adjusting handle 12. A limit assembly is provided inside the fixed base 4 at a position corresponding to the limit holes 14.

[0027] The limiting assembly includes a hollow screw 18, which is located on the outer side of the adjusting shaft 10 near the adjusting handle 12. The hollow screw 18 is rotatably connected to the adjusting shaft 10 and to the fixed base 4. To facilitate rotation of the hollow screw 18, a limiting handle 13 is fixed to the end of the hollow screw 18 near the adjusting handle 12. An internal threaded cylinder 17 is threadedly connected to the outer side of the other end of the hollow screw 18. The internal threaded cylinder 17 is slidably connected to the fixed base 4. A connecting plate 16 is fixed to the end of the internal threaded cylinder 17 near the limiting block 11. The connecting plate 16 is slidably connected to the fixed base 4. Multiple limiting bolts 15 are fixed on the side of the connecting plate 16 near the limiting block 11 and at a position corresponding to the limiting hole 14. The limiting bolts 15 are inserted into the limiting block 11 through the limiting hole 14. A limiting slider 19 is fixed to the outer side of the connecting plate 16 and is slidably connected to the fixed base 4.

[0028] When the angle of the fixed platform 2 needs to be adjusted, firstly, the limit handle 13 is rotated, causing the hollow screw 18 to rotate. When the hollow screw 18 rotates, the internal threaded cylinder 17 connected to it drives the connecting plate 16 and the limit bolt 15 fixed to the internal threaded cylinder 17 to move away from the limit block 11. When the connecting plate 16 moves until the limit bolt 15 disengages from the limit hole 14, the limit bolt 15 releases its limit on the limit block 11. Then, the adjusting handle 12 is rotated, causing the adjusting handle 12 to drive the adjusting shaft 10 to rotate. When the adjusting shaft 10 rotates, the connecting base 9 rotates around the adjusting shaft 10, thereby allowing the connecting platform 8 and the fixed platform 2 to rotate simultaneously, and thus allowing the angle of the workpiece clamped on the top of the placement platform 5 to be adjusted.

[0029] Example 2

[0030] like Figure 5 As shown, in order to facilitate the simultaneous movement of the two clamping plates 6 in opposite or opposing directions, the clamping assembly includes a bidirectional screw 20. The bidirectional screw 20 is disposed inside the fixed platform 2 and is rotatably connected to the fixed platform 2. Both ends of the bidirectional screw 20 are threadedly connected to a movable seat 21, which is slidably connected to the fixed platform 2. A support frame 7 is fixed to the top of the movable seat 21 and is fixedly connected to the clamping plate 6. The support frame 7 is slidably connected to both the fixed platform 2 and the placement platform 5. One end of the bidirectional screw 20 extends to the outside of the fixed platform 2, and a clamping handle 22 is fixed to the end of the bidirectional screw 20 located outside the fixed platform 2.

[0031] When it is necessary to clamp the workpiece, firstly, by rotating the clamping handle 22, the clamping handle 22 drives the bidirectional screw 20 to rotate. When the bidirectional screw 20 rotates, it drives the two movable seats 21 connected to it to move relative to each other along the axial direction of the bidirectional screw 20. Thus, the clamping plate 6 moves simultaneously through the support frame 7, and the workpiece placed on the top of the placement table 5 is clamped and fixed by the movement of the clamping plate 6.

[0032] Example 3

[0033] like Figure 5 As shown, a connecting shaft 23 is fixed to the lower end of the fixed platform 2. The lower end of the connecting shaft 23 extends to the inner side of the connecting platform 8. The connecting shaft 23 is rotatably connected to the connecting platform 8. A rotating gear 24 is fixed to one end of the connecting shaft 23 located inside the connecting platform 8. A drive motor 25 is fixed to the inner side of the connecting platform 8 and near the rotating gear 24. A transmission gear 26 is fixed to the output end of the drive motor 25. The transmission gear 26 meshes with the rotating gear 24.

[0034] The design of the connecting shaft 23, rotating gear 24, drive motor 25, and transmission gear 26 allows for efficient machining of different positions on the workpiece. By activating the drive motor 25, the transmission gear 26 rotates. This rotation, in turn, drives the connecting shaft 23 via the meshing rotating gear 24. The rotating shaft 23, in turn, rotates the placement platform 5 and the workpiece located at the top of the placement platform 5 via the fixed platform 2, thus adjusting the workpiece's position and effectively improving the device's practicality and processing efficiency.

[0035] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
